Loom-SHUTTLE.

SPECIFICATIAON forming part of .Letters Patent No. 702,703, dated June 17, 1902. Application tiled December 11, 1901, Serial No..85.43. (No model.)

vzen of the United States,residing at Wilkin-f sonville,'in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is aspecieation.

My invention relates to loom-shuttles, and

the spring which holds the spindle in itslowered or` raised position is contained-within.

the shuttle and not on the outside of the'shuttle. The spindle on which the @opor bobbin is supported is preferably what is termed a split spindle.`

The object of myinvention is to improve upon the ordinary construction of the spring device which holds the spindle in its lowered Ior raised position inthe class of Shuttlesl above referred to and tomake the base or pivoted end of the spindle of substantially face to be engaged by the spring device when the spindle is in its raised position. K

My invention consists lin certain novel features ofconst-ructi'on of my shuttle, 'as will be hereinafter fully described lteferringto the drawings, Figure is a side View of one end of a shuttle, partly in section, showing my improvements and the spindle in its lowered position. Fig. 2 corresponds to Fig. 1, but shows thespin'dle in its Fig. 3 shows the spindledetached. Fig. 4 shows the spring-actuated pindetached. Fig. 5 isan end view of the head of the pin looking in the direction of arrow d, Fig. 4. Fig. V6 corresponds toFig. -1, but shows a `modified construction of the spindle.

Fig. V7 corresponds to Fig. G, but shows the spindle in itsraised position. Fig. 8 shows `the spindle in Fig. detached. Fig. 9 shows the spring-actuated pin detached; and Fig. 10 shows an end view of the pin shown in Fig. 9 looking in the direction of-ar row b, same figure.' .f l

In the accompanying drawings, l is a portion of the shuttle-body, having the ordinary cavity l for the iilling,carried on the spindle 2. Thebase 2"o'f the' spindle 2 extends in a slot or recess l", leading'out of the end ofthe cavity l and of `less width than said cavity, and is pivoted onv a pin 3, extending ytransversely in the Ashuttle-body in the ordinary way.

when thespindle is in its lowered position, as shown in Fig. l, and havingthe'heel or end a' to be 'engaged yby the head of the spring-` actuated pin 4 when the spindl'eisl in its loW- ered position, and' also-the single plane'sn'rface af, extending above the heel c to be also engaged by the head ofthe pin 4 when the spindle 2 is in its raised position, as shown inFig.2. l

The spring-actuated pin 4 extends in a reencircles the body of the pin 4" and is confined between the end of the recesso and the head 4 on the pin 4'and acts to force out- Wardlythe pin 4. l l j y f l'lhe pin 4, Figs. 4 and 5, has an enlarged dat end or head 4', having an odset or extension 4^on one side oredge thereof.

the head 4 to receive the heel or extension a. on the base 2 of the spindle 2 when 'the spindle is in itslowered position. (SeefFig'l.)

- The upper or outer surface c on the offset or extension 4l is preferably Vvmade inclined, as shownin Fig. 4, .to engage and Abearon the plane surface a" @n the base 2 of I:he spindle Fig. 2.

The operation of my improvements (Shown in Figs. 1 to 5, inclusivelfwill be readily unthe spindle 2 is in its lowered position, Fig. l, the extension or heel o. will extend into the angular recess c in the head 4 of the pin A4, l

and the spring 6 actuates the pin 4 to force it outwardly andcause its head 4' toy bear onv 'cess within the end of theshuttle-body and y Y Yleading out of the recess l/, and a spring 6, 'in this instance a spiralexpansion-spring,

The offset4/ Vforms, with the head 4', an angular recess c in '2 when `the spindle is raised,'as Ashown in thebase 2( of the spindle 2 above its pivotpoint and hold the extension ct on the base 2 i 9o derstood by those skilled in the art. Vlhen v,

in contact with the wall l" of the recess l', as shown in Fig. I. Vhen the spindle 2 is raised, the extension a moves on the [iat head 4 of the pin 4 away from the ottset 4 until it reaches a point in line with or a little below its pivot-point, in which position the upper or outer surface c of the offset 4 will engage and bear on the plane surface a" on the base 2 of the spindle 2 above its pivotpoint, as shown in Fig. 2, and stop the further raising of the spindle. The spring-actuated pin 4, with its head 4' bearing on the heel or extension a on the base 2 of the spindle 2 in aline with or just below its pivotpoint, will hold the spindle 2 in its raised position, as shown in Fig. 2.

I will now describe the modified construc tion of my improvements. (Shown in Figs. 6 to l0, inclusive.) The construction shown in these figures is substantially the same as the construction shown in the previous iigures, and therefore the saine figures and letters of reference are employed on corresponding parts. The spindle 7 in Figs. G, 7, and 8 is split through to the base and has an annular flange 7 at its lower end to engage an annular recess within the lower end of the bobbin (not shown) to retain the bobbin on the spindle in the ordinary way. The base 7ll of the spindle 7 is of a little different shape than the base 2 of the spindle 2. There is an extension a on the base 7 of the spindle 7 to engage the inclined surface orwall b of the recess l when the spindle is in its lowered position, as shown in Fig. G. There is also a heel or extension a. on the base 7" of the spindle 7, corresponding to the heel or extension a' on the base 2 of the spindle 2, and a plane surface a". The head 4' of the spring-actuated pin 4 has its offset or extension 4 of a little different shape from the offset or extension 4", Fig. 4, (see Fig. 9,) the o1tset4' being a little longer and thinner, so that it will extend beyond the plane surface a and engage the free end of the split part 7 of the spindle 7 when the spindle is in its raised position, as shown in Fig. 7, to hold said part 7' against the main part of the spindle and allow of the bobbin (not shown) being placed on the spindle. Vhen the spindle 7 is lowered, the part 7 is released and allowed to spread, as shown in Fig. G, to hold the bobbin on the spindle.

The operation of the spring-actuated pin 4 (shown in Figs. (5 to l0, inclusive,) to hold the spindle 7 in its raised and lowered posi-` tions is the same as above described in connection with the spindle 2. (Shown in Figs. I to 5, inclusive.)

Itwill be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

I. In a loom-shuttle, the combination of a shuttle-body provided with a recess, a spindle having a base and pivoted within said recess, the base of said spindle being provided with an extension, as a, in front of the pivotal connection of the spindle with the shuttle body, and a heel as a', a springpressed pin having a head bearing upon the heel,\said pin having an offset or extension and an angular :recess at the junction of the head and extension to engage the heel when the spindle is turned into the shuttle, the said offset or extension having an inclined surface to engage the base of the spindle when the latter is turned to its outward position.

2. In a loom-shuttle, the combination with the spindle, having its base pivoted within a recess in the shuttle-body, and an extension on the base in front of its pivot-point, to engage a wall of the recess, and an extension or heel back of the pivot-point, and a plane surfaceabove said extension or heel, of a spring-actuated pin extending in a recess in the shuttle-body at the rear of the spindle, said pin having on its head or end, which engages the base of the spindle, an offset or extension having an inclined surface and forming a recess to receive the heel of the spindle, when itis in its lowered position, and the inclined outeror upper surface of the offset or extension adapted to engage the base of the spindle, when itis in its raised position, to limit the raising of the spindle, substantially as shown and described.

In a loom-shuttle, the combination with the spindle having its base pivoted within a recess in the shuttle-body, and an extension as a on the base in front of its pivot-point, to engage a wall of the recess, and an extension or heel a back of the pivot-point, said base of the spindle having a forwardly-extending plane surface above said extension or heel, a, of a spring-actuated pin extending in a recess in the shuttle-body at the rear of the spindle, said pin having on its head or end, which engages the base of the spindle, an oitset or extension forming a recess to receive the heel of the spindle, said offset or extension having an inclined surface to engage the spindle-base, and the projecting end of the offset or extension engaging the split part of the spindle, when it is raised, to hold it against the main part of the spindle, substantially as shown and described.
